Images as planes in Solid View Shading
Before any requests read the manual on using images in empties.
https://docs.blender.org/manual/en/latest/modeling/empties.html?highlight=image%20reference#image

If you want images as reference, don't use images as planes, use Add &gt; Image &gt; Reference.

This tool allows you to create an empty with an image associated with it, that ist is visible in Solid mode. It is not really an object with vertices or faces, and it will not render in the final image. Such image will appear in front of the geometry.
To have an image that shows behind the geometry, then use Add &gt; Image &gt; Background
You can always change how the image is displayed:

To resize the image to an exact size use  the Size controls for the properties of the empty.

Or use the sliders for scale to change the aspect ratio in whichever axis you need.

Images as planes is meant to be used when you need a plane with actual vertices and faces, that has an image mapped into the material.
